LTC1385CG#PBF

Drivers, Receivers, Transceivers Overview

The LTC1385CG#PBF is a 2-driver/2-receiver EIA/TIA-562 transceiver operating from a single 3.3V supply in a 20-lead SSOP package. It features ultra-low power consumption with a quiescent current of 0.5mA, dropping to 35mA in Driver Disable mode and 0.2mA in Shutdown mode. The device supports data rates up to 120kbaud and utilizes four 0.1mF capacitors for its charge pump. It provides robust protection, including receiver inputs forced to –25V without damage and ESD protection exceeding –10kV. The component operates within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated Driver Disable and Shutdown modes for significant current reduction
• Robust I/O protection allowing receiver inputs to withstand –25V and ESD events exceeding –10kV
• Compact design requiring only four small 0.1mF capacitors for internal charge pump generation

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm that the delivered components match the specified 20-lead SSOP form factor and RoHS compliance requirements before integration into production.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-power RS-562 communication in portable devices. It is suitable where space constraints limit capacitor size due to the requirement for only four 0.1mF units. Consider the 0°C to 70°C operating range; for wider industrial temperatures, consult the manufacturer for alternative part numbers such as the LTC1385IG variant.

Drivers, Receivers, Transceivers Part Context

The LTC1385 belongs to the Linear Technology (now Analog Devices) family of low-power RS-232/RS-562 transceivers. It is pin-compatible with the LT1180A, facilitating direct upgrades in existing designs. The CG suffix denotes the commercial temperature grade housed in a 20-lead SSOP package, distinguishing it from industrial variants or different physical footprints like the SOIC or PDIP options.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet lists the LTC1386 as a related part offering similar functionality in a narrow 16-pin SO package. Designers should verify pinout compatibility and electrical specifications when considering cross-model substitutions within the product family.
